I configured easy VPN on my ASA, but, when i type the following command, it gives me this error as shown:
SA-Gate(config)# crypto ipsec transform-set myset esp-3des esp-md5-hmac The 3DES/AES algorithms require a VPN-3DES-AES activation key. ASA-Gate(config)# crypto dynamic-map dmap 100 set transform-set myset ERROR: transform set with tag "myset" does not exist.
So, this issue concerning Licensed features on ASA and if so, what is all required to complete the easy VPN configuration.
The difference between them is the level of strength of the encryption algorythm. 3DES uses 3 encryption keys (created by the algorythm) while DES uses only one. In practical terms, 3DES has a 3 times longer key to encrypt data than DES, what makes 3DES a stronger method.
